I want to subclass the built-in DropDownList in ASP.NET so that I can add functionality to it and use it in my pages. I tried doing this with a UserControl but found that it doesn’t expose the internal DropDownList (logically, I guess). I’ve googled for the answer but can’t find anything.
I need a working approach of getting all classes that are inherited from a base class in Python.
The following code works:
I’m interested in subclassing the built-in int type in Python (I’m using v. 2.5), but having some trouble getting the initialization working.
Why did the Python designers decide that subclasses’ __init__() methods don’t automatically call the __init__() methods of their superclasses, as in some other languages? Is the Pythonic and recommended idiom really like the following?
I want to allow type hinting using Python 3 to accept sub classes of a certain class. E.g.:
